13.4 Replacing the Door Gasket
To avoid injuries replace the gasket while the autoclave is cold.
Pull off the gasket from the door groove and install the new gasket
referring to the drawings as above points 1, 2 and 3.
CAUTION!
See drawing below for the right direction of the gasket.
13.5 Checking the Safety Valve
(Located in the water reservoir)
In order to prevent the safety valve from becoming blocked, it is necessary
to allow the steam pressure to escape through it (every month).
To avoid injuries begin this check while the autoclave is cold.
1. Operate the sterilization cycle according to the manual.
2. Allow a pressure of approximately 200 kPa (29-psi) to build up in the
chamber.
3. Remove water reservoir cover (1).
4. Pull the ring of the safety valve using a tool, i.e. screwdriver, hook etc
and lift the safety valve ring for 2 seconds. Be careful not to burn your
hands.
5. Press the STOP key to abort operation, and allow the steam to exhaust
from chamber.
6. Wait until pressure goes down to zero, only then can the door be
opened.
